I am not sure what a "real" economy is either. It seems that government entities (lookin at you, Greece) can make up whatever rules they want and the German bankers will grudgingly support it in order to perpetuate and maintain their control. But if you are simply a group of anonymous world citizens looking for a means of exchanging things of value in a way that can't be manipulated by governments and bankers, then you are simply playing a Monopoly game.
